Another Obama Appointee Withdraws Citing Tax Troubles

President Obama’s choice for the position of chief White House performance officer has withdrawn from consideration for the post, an administration official said Tuesday, after coming forward with concerns about her tax returns.

Nancy Killefer, appointed by the president last month to a new position to scrutinize government spending, told the administration on Monday that she intended to step down from the position at the Office of Management and Budget. An administration official, speaking on condition of anonymity because the announcement was not finalized, confirmed that Ms. Killefer’s withdrawal came because of questions with her taxes. Update: In her resignation letter to Mr. Obama, she described the problem as a tax-related issue stemming from Washington, D.C. unemployment.
